I've come full circle and am back to enjoying mono Green the most at the moment. In the past, even though they were one of my two favorite colors, I wasn't too fond of their spells (except for Murkwood Allies) but now I'm super digging them. Argagarg is the bees knees now, he gives you so much offense, which is surprising from a 1 atk hero. Arg + Feral smashes stuff. I want my Centaurs vomiting rainbows all day, too strong.
Calamandra has always been cool. Murkwood Allies is still fun and her other spells can wreck in the right situation. Ferocity and Behind the Ferns is good stuff when combined with Tiny Basilisks but Ferocity becomes crazy time with Potent Basilisk.
Either of the above two heroes are solid for early game pressure stuff.
I'm only a little bit bummed that Midori is more niche then the other two heroes. He's got some situationally strong spells. I need to get better at pulling of Circle of Life shenanigans. Once Midori maxes the death lazer is cool and 1/2 () Wisps are something that I enjoy.
What do people think of Rampant Growth? I think this is one of the best tech 0 cards and if you're workering it, especially early, you're making a mistake. Being able to kill stuff and keep your stuff is what Green is all about and being able to do that off of any hero is just too good to pass up on.
I had a cool experience with Verdant Tree in a recent set of games. On a turn where I rebuilt my tech 3 I dropped the Verdant Tree (so was hanging onto it all game for this potential purpose) to force my opponent to have to blow up a 3 hp thing then the 5 hp tech building. If he couldn't pull that off then he would be getting hit in the face by an army of Squirrels soon. It was especially fun because I don't think I used the tree much, if at all, since testing.
Also Feral Tech II is better then I gave it credit for so was happy to be wrong about that. Bears are fun and Dino Sized, Raindow Lazer Bears are even more fun (take that double patrolling Voidblockers). And changed Moss Ancient as well better then I thought so glad to be wrong about the changed version as well.
One finally thing I was wrong about, that was discovered recently, is Spore Shambler has a lot more general uses then I thought.
So overall my like/enjoyment of Green is very high right now.
